The Maserati 3500 GT (Tipo 101) and the Maserati 3500 GT Convertibile (Tipo 101/C) are 2-door coupé and convertiblegrand tourers made by Italian car manufacturer Maserati between 1957 and 1964. It was a seminal vehicle for Maserati as the company's first successful attempt at the Gran Turismo market and series production.

History

Background

In the early 1950s Maserati had achieved racing success and international visibility, thanks to cars such as the A6GCM; its 2-litre, twin cam inline-six engine had already been enlarged to three litre capacity on the Maserati 300S. Chief engineer Giulio Alfieri felt the next step was to design an all-new 3.5-litre engine; the resulting long-stroke six, designed foremost for endurance racing on the Maserati 350S, was ready in 1955.[1] In the meantime Maserati's first forays into the grand tourer market, the 1947 A6 1500, 1951 A6G 2000 and 1954 A6G/54, had proven that the business was feasible; but the A6 road cars were still built in just a dozen examples a year—hardly series production. A different approach was needed to build fully accomplished grand tourers.

Development

The main development efforts that led to the 3500 GT were carried out in 1956–57, despite the frantic activity required by Maserati's participation in the Formula 1 world championship.[2] Alfieri modified the 350S's engine to suit a touring car, e.g. by switching to a wet sump oil system and changing the engine accessories.[2] He also made several business trips to the United Kingdom in order to contact components suppliers.[2] None were found in Italy, as Italian taxation system and the industry structure forced manufacturers to design every part in-house; a daunting task for small companies like Maserati.[2] Thus the 3500 GT alongside Italian Webercarburettors and Marelli ignition, used many British-made components such as a Salisbury rear axle, Girling brakes and Alford & Alder suspension parts.

Into production

Production of the 3500 GT started in late 1957; eighteen cars were built that year, the first handful leaving the factory before Christmas.[5] All 3500 GTs had leather interior and Jaeger instruments. A first Touring convertible prototype was shown at the 1958 Turin Motor Show.[6] But it was a proposal by Carrozzeria Vignale (designed by Michelotti) shown at the 1959 Salon de l'Auto in Paris that went into production as 3500 GT Convertibile. The Convertibile did not feature Touring's Superleggera construction, but rather a steel body with aluminium bonnet, boot lid and optional hard top;[7] it was also built on an 10cm (3.9in) shorter wheelbase, and weighed 1,380kg (3,042lb). Front disc brakes and limited slip differential became optional in 1959, and were standardized in 1960; rear discs became standard in 1962.

The 3500 GTi was introduced at the 1960 Salon International de l'Auto,[8] and by the following year became the first fuel-injected Italian production car. It had a Lucas mechanical fuel injection, and developed 235PS (173kW; 232bhp). The 5-speed gearbox which had been an available option since 1960 was made standard.[9] The body had a lowered roofline and became somewhat longer; minor outward changes appeared as well (new grille, rear lights, vent windows). From 1961 convertible 3500s for export markets were named 3500 GT Spyder and GTi Spyder.

In 1959, the V8-engined Maserati 5000 GT was introduced using the chassis of the 3500 GT. Also based on the 3500 GT's mechanicals was the Maserati Sebring 2+2 coupé, which entered production in 1962.

In total 2,226 3500 GT coupés and convertibles were built between 1957 and 1964.[4] The first year (1958) 119 cars were sold, while 1961 was the best-selling year, totalling 500. All together, 245 Vignale convertibles and nearly 2000 coupés were manufactured, of these, 1981 being Touring coupés, the rest were bodied by other coachbuilders: Carrozzeria Allemano (four coupés, including the 1957 prototype), Zagato (one coupe, 1957), Carrozzeria Boneschi (1962 Turin Motor Show and 1963 Geneva Motor Show ), Pietro Frua (two or three coupés, one spider) and Bertone (one coupé, 1959 Turin Motor Show).[10] The last was a coupé by Moretti (1966 Geneva Motor Show).
